I am using functions. They are already stepped. I just need to nudge 
them outward by 1/2 step, which I can't figure how to do.

Here are examples:

#declare CSolid_HSLSphere_Saturation_stepped = function { floor(6 * 
f_r(x,y,z))/6};
#declare CSolid_HSLSphere_Lightness_stepped = function { floor(12 * 
f_ph(x,y,z)/pi)/12};


I guessed and tried this with no success:

#declare CSolid_HSLSphere_Saturation_stepped = function { floor(6 * 
f_r(x,y,z))/6 + 1/12};
#declare CSolid_HSLSphere_Lightness_stepped = function { floor(12 * 
f_ph(x,y,z)/pi)/12 + 1/24};
